我试图在C中声明一个回调例程,如下所示：
- void register_rename (int (*function) (const char *current,const char *new));
- /*------------------------------------------------------------*/
- /* WHEN: The callback is called once each time a file is received and
- * accepted. (Renames the temporary file to its permanent name)
- * WHAT: Renames a file from the given current name to the specified new name.
- */
但是,我收到以下错误：
- line 204: error #70:
- incomplete type is not allowed
- void register_rename (int (*function) (const char *current,const char *new));
我不知道如何纠正这个问题.我在同一个头文件中声明了其他类似的回调例程,我没有收到此错误.
请帮忙！
